The magnetocaloric effect and its most straightforward application, magnetic refrigeration,
are topics of current interest due to the potential improvement of energy efficiency of cooling …

Phase transitions are a common phenomenon in condensed matter and act as a critical
degree of freedom that can be employed to tailor the mechanical or electronic properties of …

Magnetic refrigeration relies on a substantial entropy change in a magnetocaloric material
when a magnetic field is applied. Such entropy changes are present at first‐order …

Martensitic materials show a complex, hierarchical microstructure containing structural
domains separated by various types of twin boundaries. Several concepts exist to describe …

The variety of the multifunctional properties of martensitic Ni-Mn based Heusler alloys are
related to the presence of a magnetostructural transition. We report here on a new …

Heusler alloys exhibiting magnetic and martensitic transitions enable applications like
magnetocaloric refrigeration and actuation based on the magnetic shape memory effect …

Materials design based on density functional theory (DFT) calculations is an emergent field
of great potential to accelerate the development and employment of novel materials …

The precise determination of the stability of different martensitic phases is an essential task
in the successful design of (magnetic) shape memory alloys. We evaluate the effect of …

Pathways connecting dissimilar crystal structures are fundamental to our understanding of
structural phase transitions. In this Letter, we report on a new pathway connecting the …

Segregation in a series of Ni 2 Mn 1+ x (In, Sn, Ga, Al) 1− x and Mn 2 Ni 1+ x (Ga, Al) as well
as Ni 2+ x Mn 1− x Ga Heusler alloys is studied by first-principles calculations. We show that …
